我有多个自定义帖子类型，每个都有多个类别。我试图用这段代码显示所有自定义帖子类型+常规帖子中的某些类别。
<?php query_posts( array(
\'post_type\' => array( \'post\', \'miss_behave\',\'emily_davies\', \'gemma_patel\', \'poppy_smythe\' ),
\'tax_query\' => array(
\'relation\' => \'AND\',
array(
\'taxonomy\' => \'category\',
\'field\' => \'term_id\',
\'terms\' => 4
),
array(
\'taxonomy\' => \'miss_behave_category\',
\'field\' => \'term_id\',
\'terms\' => 141
),
array(
\'taxonomy\' => \'emily_category\',
\'field\' => \'term_id\',
\'terms\' => 142
),
array(
\'taxonomy\' => \'gemma_category\',
\'field\' => \'term_id\',
\'terms\' => 143
),
array(
\'taxonomy\' => \'poppy_category\',
\'field\' => \'term_id\',
\'terms\' => 144
)
),
\'showposts\' => 4)
); if (have_posts()) : ?>
这样页面就不会显示任何内容。仅当我仅查询默认帖子时，页面才会显示一些内容。
请帮忙！

我想出来了。将“关系”设置为“或”很重要。
<?php $myquery[\'tax_query\'] = array(
\'relation\' => \'OR\',
array(
\'taxonomy\' => \'category\',
\'terms\' => array(\'home-slides\'),
\'field\' => \'slug\',
),
array(
\'taxonomy\' => \'miss_behave_category\',
\'terms\' => array(\'home-slides-1\'),
\'field\' => \'slug\',
),
array(
\'taxonomy\' => \'emily_category\',
\'terms\' => array(\'home-slides-2\'),
\'field\' => \'slug\',
),
);
query_posts($myquery);
?>
